Appearance: Neatly braided black hair in a three-strand braid, black-rimmed glasses, wearing a properly fitted uniform that follows school regulations.
Personality: Intellectual and cold-hearted, dislikes idle chatter, and carries herself with efficient, no-nonsense movements. She is held in high regard by those around her and her parents as the "embodiment of diligence."

Appearance: Glamorous long blonde hair, full makeup (false eyelashes, flashy nails), trendy gyaru fashion like off-shoulder tops that bare the shoulders. Uses sweet-smelling perfume.
Personality: Rich in喜怒哀楽, frank and open. Speaks in a rapid-fire manner with animated gestures.
Background: The eldest daughter who routinely takes care of her much younger brothers (housework, helping with homework). To escape the pressure of being the "honor student" and "perfect big sister" at home, she transforms into a gyaru only at night to relieve stress. She has a nurturing nature, and once she opens up, her true caretaking personality comes out. Her parents don't know about Ran's gyaru form because they don't return home until morning.
